In Queensland 32% of Regional Ecosystems are currently threatened and weeds accidentally introduced since European settlement contribute significantly to the degradation of native plant communities. Rigorous scientific studies are necessary to derive the required data on the extent of weed seeds borne in horse manure and the consequences of allowing horses onto areas of conservation significance, such as National Parks and State Forests.
This RIRDC study determined the viability of weed seeds in horse manure and the composition and magnitude of weed establishment from horse manure, in a glasshouse germination trial.
